Flat Roof Installation. It’s the technique that fails, not the material. Wilton – Greenwich

There are many techniques to install rubber roofs. In Greenwich Connecticut, some people prefer the most expensive roof materials. Every roofer has there own ways. The issue is to make a roof last and never leak. Easier said than done. After installing flat roofs and repairing them for the last 25 years, we have developed a sound technique that can make a roof last 30 years or more.

EPDM rubber seams are coming apart.

Choice of Rubber Roof.

It is important to have to right choice of materials. There are basically three different flat roof membranes to choose from. Every roofing company will sell up and sell down on what they are comfortable with.

Most roofing companies will push EPDM rubber as the choice for a membrane. The selling point is that there are fewer seams and therefore will have a better chance not to leak. The other point is the appearance. I agree it is pleasing to the eye.

The reason why we don’t  prefer EPDM membranes is because of several issues. Watch the short videos on what we mean by EPDM rubber problems.

EPDM Rubber Problems

The issues are:

  1. Wherever the seams are, the tend to separate after time and leak.
  2. The glue that is used to keep the seams together, disintegrate over time by the heat of the sun, causing the roof to fail.
  3. The weather conditions are not always favorable to install EPDM membranes. Humidity and temperatures play a big role in the quality of the installation. A roofing company will install a roof regardless of what is favorable for the material. They after the money.
  4. The EPDM rubber is not protected against ultraviolets. It will not last that long.
  5. Most of the time an EPDM roof will fail at the flashing. The adhesives used to adhere the rubber to metal is not 100% fool proof. We repair many such roofs.
  6. If someone would accidently make a hole or a branch would tear into the roof, then you could not use any TAR product to make a repair – this happens all the time. Inexperienced handyman and workers making repairs with tar.

We recommend Modified Bitumen Torch down membrane as a Flat Roof Membrane for the following reasons:

  1. Easier to install.
  2. Can almost install the membrane over any surface including a gravel roofs.

    This is what a Modified Bitumen membrane can do, it can hold water without leaking, unlike an EPDM rubber.

  3. Comes with Ulta Violet protection in the farm of minerals embedded in the material.
  4. It installs almost in any temperature. 30˚F  to 120˚ F is perfectly ok to work with the material.
  5. The seams are heat welded together. The material melts into each other and therefore can’t separate.
  6. Any person can make repairs in an emergency by using TAR. It’s compatible with any petroleum products.
  7. Adhering it to metal flashing has a stronger and better bond than any other material.
  8. Less preparation to install.

Watch the video how we made a quick installation on a roof in Greenwich of a Modified Bitumen Membrane over a gravel roof. this can’t be done with an EPDM or TPO roof.

No matter who the roofing company is and what material is used, it’s the installation technique that will make or break a roof.
